SPECIFICATION formingpart of Letters Patent No. 661,795, dated November 13, 1900.

Application filed June 23, 1900. $erial No. 21,295. (No modeld T0 at whom, it may concern.-

Beitknown that LCHAELEs T. ELLswoR'rH, a citizen of the United States, residing at Forest City, in the county of Winnebago and State of Iowa, have invented certain new and useful Improvements in Kinetoscopes; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in kinetoscopes or movingpicture machines; and it consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described,and particularly pointed out in the appended claim.

The object of the invention is to provide a construction of machine in which rolls or drums carrying a series of pictures are mounted upon a shaft which is adapted to be readily and conveniently detached for the substitution of other consecutive-view pictures.

The invention is illustrated in the accompanying drawings, in which Figure l is a perspective View of my improved moving-picture machine, and Fig. 2 is a central vertical longitudinal section of the same.

Referring now more particularly to the drawings, in which like reference characters designate corresponding parts throughout both views, the numeral 1 represents the easing or cabinet of the apparatus, which incloses the picture mechanism and which is preferably, as shown, rectangular and of oblong form and provided at its upper front edge with a longitudinal concavo convex glass or other transparent panel 2, through which the operation of the picture mechanism may be viewed for the purpose of detel-mining whether or not it is in perfect running order. Mounted in suitable bearings in the end walls of the case or cabinet and extending longitudinally therethrough is a shaft 3, on which are mounted duplex drums or cylinders 4, each carrying a series of pictures 5, adapted to be consecutively exposed by the rotation of the shaft and drums through the lenses 6, mounted in the front wall of the cabinet in the usual manner. The pictures 5 extend radially at right angles to the major axes of the drums l and are adapted as each comes into position to be viewed to strike against a thin wire 8 or other suitable tapping device extending longitudinally of the cabinet to bring theminto the proper position to be viewed and to impart a slight vibratory movement to the pictures to enhance the effect of the view upon the eye of the observer. The shaft 3 is adapted in practice to be placed in position through slots 9,formed in the end walls of the case or cabinet, whereby said shaft and the drums may be quickly and conveniently removed for the substitution of a new shaft and drums or the application of a new series of pictures thereto. The shaft 3 may be driven and the speed of its revolution controlled through the medium of any suitable construction of drive-gearing and governor mechanism. In the present instance I have shown a motor mechanism comprising a drive-shaft 10, extending longitudinally at the top of the case or cabinet in the rear of the glass panel 2. This drive-shaft carries at one end a belt wheel or pulley 11 for the reception of the drive-belt 12, which also passes around a smaller pulley-wheel or pulley 13, arranged upon the adjacent end of the shaft 3, whereby the latter receives motion from the said shaft 10. Near the opposite end of the shaft 10, which projects outwardly from the case or cabinet, is secured to said case or cabinet a bracket or casing 1e, within which is arranged a coiled spring 15, having one end made fast to the said bracket or case or to the cabinet and the other end suitably connected to the end of the shaft 10. To this end of the shaft is also connected a crank-handle 16, whereby the shaft may be revolved to wind up the spring 15 and to prevent retrograde movement of the shaft under the action of the spring. A ratchet-wheel 17 is fixed thereto and is adapted to be engaged by a pawl 18, which allows the shaft to rotate freely in the direction in which it is turned to wind up the spring, but prevents turning of the shaft in the reverse direction. Upon releasing the pawl the spring is left free to unwind and in unwinding operates the shaft 10, which in turn communicates motion through the medium of the pulleys ll and 13 and belt 12 to the shaft 3 and drums 4:, as will be readily understood. To regulate the motion of the operating-pictu re mechanism, governor mechanism is provided, the same consisting of a shaft 19, mounted to retate in sectional boxes 20, secured to the easing or cabinet 1 and carryingatits lower end a hevelgear 21, which meshes with a corresponding gear 22 upon the opposite end of the shaft 3 from the belt wheel or pulley 1%. The governor 23, which is of the centrifugal type, is arranged upon the upper end of the shaft 2st and is composed of a ball 25, secured to said. shaft, and two sets of movable arms 26, pivoted to each other and carrying balls 27, the upper memherof each set of arms being adjustably mounted upon the shaft 24 through the medium of a nut or adjusting collar 28, whereby the operation of the governor may be regulated as desired.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

In a machine of the character set forth, the combination with a casing or cabinet provided with slots, of a shaft adapted to be applied and removed through said slots, and drums arranged upon the shaft and carrying pictures adapted to be consecutively displayed, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES T. ELLSWORTH.
